Propagation of heavy cosmic-ray nuclei

Abstract

Techniques for modeling the propagation of heavy cosmic-ray nuclei, and the required atomic and nuclear data, are assembled in this paper. Emphasis is on understanding nuclear composition in the charge range 3 < Z < 83. Details of the application of "matrix methods" above a few hundred MeV per nucleon, a new treatment of electron capture decay, and a new table of cosmic-ray - stable isotopes are presented. Computation of nuclear fragmentation cross sections, stopping power, and electron stripping and attachment are briefly reviewed.
